Hey, I am going ahead to the social square and we have a special guest and going to go this way. Here on "The heat index" jiff doesn't have a big announcement. He's going to show off with a couple of tricks. If you have ever met jiff he is a big star on social media and can do a lot of cool things. He will show us one right now. And I believe this is a first time that we're going to do this, so, jiff, do you want to go ahead and do you want them to tell him how to do his autograph. Go ahead, jiff. Big moment. Yeah, are you going to do it? I'm afraid. I don't want to interrupt. He's like a big movie star right now. Do you want to come in? Autograph. Autograph. All right. There you go, jiff. We got the autograph. Give me, five, buddy. Here's here kicking off our dog versus dog contest. Send us videos to goodmorningamerica.com on Yahoo! And the top dog will scare off dog to dog right here, right here in times square. You know what, he doesn't have to do it. He doesn't perform on command. But there are the rules right there. Hope to hear from you. As I said there were so many people who sent adorable pictures of their dogs saying that they could match jiff paw for paw. He just had to find his motivation. Exactly. He's proven now. Next up in our "Heat index."
